Abstract

A blank and method of folding for forming a box for granular material such as soap and the like including one piece of stock material having a first series of panels for forming outer walls of the box and a second series of connected panels for forming a liner within the box. The box includes top and bottom end flaps on each of the outer panels of substantial length for substantial overlapping of the end flaps to create a secure seal at both the top and the bottom ends of the box. The box also includes a tear strip opening and a resealable cap structure which is formed after the tear strip is removed.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A box for forming a package for granular material, said box comprising: a) a first series of connected panels for forming outer walls of the box;   b) a second series of panels forming a liner within said box;   c) said first series of panels including connected first, second, third and fourth panels;   d) said second series of panels including first, second and third panels;   e) each of said panels of said first series including a pair of oppositely positioned closure flaps for forming the top and bottom ends of the box;   f) a tear strip disposed on at least three of said outer walls of said box, said tear strip being located between said top and bottom ends of said box, said tear strip defining a cap above said tear portion and defining a main body below said tear portion;   g) a first angled knife cut initiating said tear strip, said first angled knife cut being disposed on one of said at least three outer walls;   h) a second angled knife cut terminating said tear strip, said second angled knife cut being disposed on another one of said at least three outer walls distant from said first angled knife cut;   i) each said first and second angled knife cuts preventing tearing into a fourth one of said outer walls; and   j) wherein removal of said tear strip causes said cap to substantially separate from said main body while said first and second angled knife cuts prevent further tearing into said fourth one of said outer walls of the box during repeated opening and closing of said box by moving said cap toward and away said main body for accessing the granular material.   
     
     
       2. The box as set forth in claim 1, further comprising: a) said tear strip formed in said second, third and fourth panels.   
     
     
       3. The box as set forth in claim 1, wherein: a) said tear strip is formed by a pair of offset lines of weakness.   
     
     
       4. The box as set forth in claim 3, wherein: a) said lines of weakness are formed by two offset pairs of cuts.   
     
     
       5. The box as set forth in claim 1, wherein: a) some of said closure flaps extend substantially entirely across the width of said box.   
     
     
       6. The box as set forth in claim 5, wherein: a) all of said closure flaps are nearly the same height.   
     
     
       7. The box of claim 1, wherein: a) some of said closure flaps include embossed portions thereon.   
     
     
       8. The box of claim 1, wherein: a) some of said closure flaps include debossed portions thereon.   
     
     
       9. A blank for forming a box for packaging granular material, said box comprising: a) a first series of connected panels for forming outer walls of the box;   b) a second series of panels for forming a liner within a box;   c) said first series of panels including connected first, second, third and fourth panels;   d) said second series of panels including first, second and third panels;   e) each of said panels of said first series including a pair of oppositely positioned closure flaps for forming the top and bottom ends of the box;   f) a tear strip disposed on at least three of said first series of panels, said tear strip being locatable between top and bottom ends of a box, said tear strip defining a cap above said tear portion and defining a main body below said tear portion;   g) a first angled knife cut initiating said tear strip, said first angled knife cut being disposed on one of said first series of panels;   h) a second angled knife cut terminating said tear strip, said second angled knife cut being disposed on another one of said at least three panels of said first series of panels and distant from said first angled knife cut;   i) each said first and second angled knife cuts preventing tearing into a fourth one of said first series of panels; and   j) wherein removal of said tear strip causes the cap to substantially separate from said main body while said first and second angled knife cuts prevent further tearing into the fourth one of the outer walls of a box during repeated opening and closing of a box by moving the cap toward and away from the main body for accessing the granular material.   
     
     
       10. The blank for forming a box for packaging as set forth in claim 9, wherein: a) some of said flaps connected to panels of said first series include tapered gullets formed therein; and   b) said tapered gullets include angled portions for maintaining a closed seal when the blank is formed into a box.   
     
     
       11. The blank for forming a box for packaging as set forth in claim 10, wherein: a) some of said flaps are free of tapered gullets.   
     
     
       12. The blank as set forth in claim 9, wherein: a) a fold line is defined between each one of adjacent first second, third, and fourth panels; and   b) only a single one of said tapered gullets is located adjacent one of said fold lines.   
     
     
       13. The blank as set forth in claim 9, wherein: a) said first panel is larger in width and height than said second panel.   
     
     
       14. The blank as set forth in claim 9, wherein: a) said tear strip is formed in said second, third and fourth panels.   
     
     
       15. The blank as set forth in claim 9, further comprising: a) a pair of intermediate panels connecting said first series of panels to said second series of panels.   
     
     
       16. The blank as set forth in claim 15, wherein: a) said intermediate panels are connected by a fold line which is both perforated and scored for facilitating folding of said panels together.   
     
     
       17. The blank as set forth in claim 16, wherein: a) said intermediate panels include one panel having a glue strip thereon for adhering to the other intermediate panel.
